Just a heads up... you cannot use the Predator on a 2005 to adjust for different ring & pinion gears. I had one shipped to me for that sole purpose (and to adjust for LT headers) and found out today that it can't address either issue.
I put 3.91s in and need to adjust for the new ratio since my speedometer is off. Any recommendations?
